R2* imaging of transfusional iron burden at 3T and comparison with 1.5T.

Purpose: To determine normative R2* values in the liver and heart at 3T, and establish the relationship between R2* at 3T and 1.5T over a range of tissue iron concentrations.

Materials And Methods: A total of 20 healthy control subjects and 14 transfusion-dependent patients were scanned at 1.
